Link pontoon-bridge park

 

(57) Abstract:

The invention relates to crossing-bridge means, and more particularly to floating bridges and ferries. Link pontoon-bridge Park includes pivotally connected two extreme 1 and two medium 2 pontoon dened in the plane of modelsport transverse partitions separating each pontoon into two Autonomous pressurized section, and a butt joint 5 located at the ends of the pontoons. The new link is the fact that sections of the pontoons made with the possibility of changing the distance between them through the mechanism of the extension, and between sections of the middle pontoons placed the power of the frame 13 and the upper and lower power telescopic beams 12, rigidly connected to one ends of the power frames in their corners, and the other with medium sections of the pontoons by means of the locking mechanism, when this link is equipped with ramps 7 laid on top of the power telescopic beams. The mechanism sections made in the form of two parallel installed in the educated sections of the middle pontoons niche cylinder 16, the piston rod of each of which is attached to the power rack 13 and the case - to the cross beam section of the pontoon. The locking mechanism in the s beam 12. Technical solution allows to reduce the set of pontoon-bridge Park number of units, vehicles and the number of service calculations required for pickup floating bridge. 2 C. p. F.-ly, 7 Il.

The invention relates to crossing-bridge means, and more particularly to a floating bridges and ferries.

Known river link tactical pontoon Park, USA [1] contains pivotally connected outer and middle pontoons butt nodes.

A disadvantage of the known river link is its short length.

It is also known river link pontoon-bridge Park MSP [2] containing pivotally connected two outer and two middle pontoon, equipped with butt nodes that are installed on the ends of the middle pontoons.

The disadvantage of this river link is its small length, which requires a large number of links for pickup floating bridge across water obstacles of a width exceeding 50 m In the case of simple constructive extend the length of the link increases its weight, which makes the link not transportable by car according to the criteria of capacity and maneuverability.

Object of the invention is I the th bridge.

The solution of the stated problem is achieved by the fact that at the level of the pontoon-bridge Park, including the United articulated two outer and two middle pontoon is placed within the cross beams and mounted in the plane of modelsport transverse partitions separating each pontoon into two Autonomous pressurized section, and the joint nodes located at the ends of the pontoons, section configured to change the distance between them through the mechanism of the extension, and between sections of the middle pontoons placed the power of the frame and the upper and lower power telescopic beams, rigidly connected to one ends of the power frames in their corners, as with other sections of the middle pontoons through mechanisms fixation, when this link is equipped with ramps, laid on top of the power telescopic beams. The mechanism sections made in the form of two parallel installed in the educated sections of the middle pontoons niches of the cylinders, the piston rod of each of which is attached to the power rack and the chassis cross beam section of the pontoon. When the locking mechanism is made in the form of dip figured finger, simultaneously closing the upper and lower telescopic BA is increased to 10 m Thus, for pickup floating bridge length 227 m, which is assembled from a pontoon-bridge Park MSP, will require more than 32 river level, while only 22, that is, 1.5 times less. This in turn will reduce the number of vehicles to transport links to 10 units, and service calculations for 30 people.

The invention is illustrated by drawings, which depict: Fig. 1 open the link pontoon-bridge Park when not expanded sections, plan, and Fig. 2 open the link with separated sections, plan, and Fig.3 is the same, no set of ramps; Fig.4 open the link, side view; Fig. 5 section a-a in Fig.4; Fig.6 ramp, side view; Fig.7 dip curly finger.

Link pontoon-bridge Park includes pivotally interconnected at the pontoon 1, the average pontoons 2 and 3, at the pontoon 4, butt nodes 5, 6 mounted on the ends of the middle pontoons, and four ramps 7. At the pontoons 1, 4 and medium-sized pontoons 2, 3 respectively separated on a stand-alone sealed sections 8, 9, 10, 11, and the corresponding sections 10, 11 medium pontoons 2, 3 interconnected at the ends by the force of the telescopic beams 12, made in the form of pipes. Between sections 1 is Linyi links 14. The rectangular frame is made of Tauris beams and corners are rigidly connected to power telescopic beams 12. For separation of adjoining sections is applied extension mechanism containing two parallel installed in the recesses 15 of the adjacent sections 10 and 11 of the hydraulic cylinder 16, the piston rod of each of which is attached to the power frame 13, and the body to the cross beam 17 of the section of the pontoon. Each section 10 and 11 are two of the locking mechanism of power telescopic beams 12, with one dip curly finger 18, simultaneously closing the upper and lower telescopic beams 12.

The claimed device operates as follows.

Link pontoon-bridge Park is unloaded from the pontoon car on water and disclosed. Then removed all the dip curly fingers 18 of the locking mechanism of power telescopic beams 12 and by means of hydraulic rams 16 two groups of adjacent sections 8, 9, 10, 11 are moved apart in the end position, in which the fingers 18, trailing both the upper and lower power beams 12. Further, the gap between groups of adjacent sections is laid ramp 7, each ramp special sockets, carried out the 2 or 3. After this link is introduced into the line floating bridge manually or using a tow-motor boats. Translation link in the transport position in the reverse order.

1. LINK PONTOON-BRIDGE PARK, including the United articulated two outer and two middle pontoon is placed within the cross beams and mounted in the plane of modelsport transverse partitions separating each pontoon into two Autonomous pressurized section, and connecting the nodes located at the ends of the pontoons, characterized in that section made with the possibility of changing the distance between them through the mechanism of the extension, and between sections of the middle pontoons placed the power of the frame and the upper and lower power telescopic beams, rigidly connected to one ends of the power frames in their corners, and with other sections of the middle pontoons through mechanisms commit when this link is equipped with ramps, laid on top of the power telescopic beams.

2. The link under item 1, characterized in that the mechanism sections made in the form of two parallel installed in the educated sections of the middle pontoons niches of the cylinders, the piston rod of each of Katarina fact, the locking mechanism made in the form of dip figured finger, simultaneously closing the upper and lower telescopic beams.
